I Application filed August 23 1900. flerial No. 27,837. (No model.)

To an whom it may concern:

Be it known that I, JAMES W. DERBY, a citizen of the United States, residing at Bowling Green, in the county of Wood and State of Ohio, have invented a new'and useful Snow- Plow,of which the following is a specification.

This invention relates to a novel snow-plow designed particularly for the clearing of railway-tracks, but capable of use in various other connections. I

The object of the invention is to produce a plow adapted to be propelled by horse-power or by a mechanical motor and equipped with elevating mechanism arranged to deposit the snow and ice upon a lateral conveyer for delivery at a point beyond one. side of the plow or upon'a supplemental elevator extending rearwardly from the plow to effect the delivery to a receptacle behind the plow--as,for instance, a car employed to propel the apparatus and to receive the snow and ice removed froin'the track. r I

In a somewhatmore specific aspect anvobject of the invention is to so relate the supplemental elevator and the lateral conveyer that the snow will ordinarily be deposited upon the supplemental'elevator, 'whichlatter, is detachably mounted in aiplane intermediate of the upper end of the elevator and the lateral conveyer in 'order that by its removal the snow will be deposited directly from the elevator into the lateral conveyer when it is desired to deposit the snow along the side of the tracks. a

To the accomplishment of these objects and others subordinate thereto, as will hereinafter more fully appear, the invention is comprehended in the preferred embodiment there of to be described, illustrated in the accompanying drawings, and succinctly defined in the appended claims.

In said drawings, Figure 1 is a perspective view of my snow-plow complete. Fig. 2 is a sectional View thereof. Fig. 3 is a sectional view in a plane at right angles to Fig. 2, and Fig. 4 is a detail view illustrating the mechanism for regulating the inclination of the lateral conveyer.

Referring to the numerals of reference employed to designate corresponding parts rigidly retained in properly-spaced relation by a number of transverse beams 2 and supporting an inclined elevator-frame 3, extending upwardly from a point adjacent to the front ends of the beams 1 and terminating at a considerable elevation, as shown. The under sides of the beams l are provided at their forward ends with runners 4, which may rest directly upon the ground or tracks or may be elevated slightly thereabove by truck-wheels 5, as shown in Fig. 2. The front ends of the runners 4 and beams 1 are severed at an angle, as shown, to form a seat for the plow or scoop 6, extending upwardly across the lower end of the frame in a plane parallel with the upper surface of the elevator-frame, so that snow and ice may be deposited from the plow upon the endless conveyers or elevators 7 and 8 movable over the face of the frame 3 to edect the elevation of the snow for deposit upon a,

supplemental elevator 9 or a lateral conveyer 10, as the case may be. 1 v

The front edge of the plow 6 is preferably tipped by a steel or other suitable shoe 11,

and at the sides of Itheplow are provided upstanding longitudinal cutters 12, having their upperedge's sharpened, as shown, and extended along the sides of the elevator-frame to the upper or rear end thereof, as shown, to

impart a receptacle-like form to the face of the plow by rotary breakers 15, extending radially from breaker-shaft 16, journaled in suitable bearings 17, preferably mounted upon the rails 12. The shaftlfi passes through the upper end of the share or stationary breaker 14, which is cutaway to form a housing 18 for a sprocket-wheel 19, mounted onthe shaft 16 and geared, as by a sprocket-chain 20, to the lower elevato'r shaft 21 through the medium of a second sprocket-wheel 22. The shaft 21 is also provided with sprocket-wheels 23 for the reception of the conveyer-chains 24 These divided sections of the material are decimated at the upper end of of the conveyors 7 and S, which chains at the upper end of the conveyor are passed around sprockets 25, mounted upon the upper elevator-shaft 26, suitably journaled in the elevator-frame and geared, as by a sprocket-chain 27, with a transverse shaft 28, journaled in suitable bearings below the elevator.

Motion is imparted to the shaft 28 through a sprocket-chain 29 upon a transverse shaft 30, geared to the driving-shaft- 31 of the apparatus, said last named shaft preferably having keyed thereon a pair of tractionwheels 32, which support the apparatus at the rear and serve to operate the shaft 31 as the device is propelled. Obviously, however, the driving-shaft 31 might be operated by a mechanical motor or other suitable means, and the form and arrangement of the gearing may be varied in many respects.

At the rear end of the elevator-frame is detachably mounted the supplemental elevator 9, comprising a short frame-section 33 and an endless conveyor 34, one shaft 35 of the lat-.

ter being provided with a sprocket-wheel 36, geared, as by a sprocket 37, to a sprocket 38 upon one end of the shaft 28 and preferably, although not necessarily, beyond thev side of the frame. The lower or front end of the supplemental elevator'9 is located directly under 35 V elongated hangersil,perman'entlycarried by the upper or rear end of the elevator and is detachably connected to the elevator frameas, for instance, by books 3.9 engaging the staples 40 extending therefrom. When in=-place, as shown. in Fig.1 of the drawings, the upper end of the supplemental elevator is suspended by the frame 33 and having their opposite extremities hooked for engagement with the staples 42. at opposite. sides of the frame 3. As heretofore stated, the supplemental elevator is, designed for use, when it is desired to convey the elevated snow and ice to, are: ceptacle+as, for instance, a car located behind a plow; but it is mounted detachably at a point intermediate of the elevator and the lateral conveyer 10 for the purpose of permitting its removal to cause the snow andioe to be delivered from the elevator to the lateraliconveyerfor delivery beyond one side of theplow. The lateral conveyer 10 is therefore permanently supported at the rear end of the frame-as, for instance, by journaling the opposite ends of one of the conveyorshafts 43 uponv the frame 3 and upon a standard 44, the lateral conveyer being disposed acrossthe frame and having its end opposite the shaft 43 extended beyond the side of the apparatus and disposed between the rear end of the frame 3and asecond standard 45.

Suitably journaled above the projected or free end of the lateral conveyer I provide a conveyer-supportingshaft 46, upon which are wound cables. 47, connected to the free end of the frame of the lateral conveyor and designed as the shaft isrotated to be wound upon the shaft 46 for thepurpose of elevating or depressing the free end of the conveyer face of the scoop ii. longitudinal cutters l2 and the heavy share 10 in order to efiect the delivery of the snow and ice at any point desired. The driving of the lateral couveyer may be effected in any suitable manner, but I prefer to mount a sprocket 48 upon one end of the shaft 43 for engagement with a sprocket-chain 49, passed around a sprocket 50 upon a shaft 51, geared, as by bevel-gears 52, to the driving-shaft 31.-

The conveyor or adjusting shaft 46 is pref-" erably operated by a crank 53' and is retained by paWl-and-ratchet mechanism 54. In order to protect the working parts of, the device from the material handled, the housing 18 in the share orstationary cutter is closed by slot ted guard-plates 55, and the conveyor-chains, located adjacent to the side rails 12, are cov ered by longitudinally-disposed overhanging guards or sheds 56, extending laterally from said rails, the rear end of the intermediate rail 13 overhanging and serving as a guard for theconnection between the sprocket-chain 27 and the shaft 26.

The operation of my device is as follows: Assuming the supplemental elevator 9 to be attached, asiillustrated in Fig. 1, and the plow to be pushed by a suitably-driven car, the shoe 11- will rest upon or immediately above the tracks, and the advancement of the plow will cause the snow and ice to be detached and forced upwardly over the inclined sur- The cutting edges of the 14 will divide. the debris'of the sections toifacilitate their delivery to'the endless conveyers 7 and 8 of the elevator, and as these sec-V tions are being delivered from thesplow to the elevator the rotary breakers; or cutters 15 will effectually loosen the, ice: and. snowto facilitate the operation of the conveyers and the deliveryof thematerial to the sup plemental elevatorwfor conveyance to the car or other receptacle. It, will beevident that the continuation of the cutters 1 2 and 13 throughout the length of the plow and elevafor will permit the apparatus to operate effectually for theremoival of snow and ice. of considerable depth, the capacity of the machine being limited only, in fact, by theelevation or height of the upper end of the elevator.- If now it is; desired: to deposit the material at one side of the apparatus, the supplemental elevator 9 is removed, and the snow and ice delivered from the upper end of the elevator will gravitate upon the lateral 'conveyer 10 and will be conveyed thereby to a point beyond the. side of the device. The elevation at which the lateral conveyer will deliverthematerial may be readily deter mined by'operating the shaft 46 to raise or lower the' free end of the conveyer 10, as desired.

From the foregoing it will be observed that I have produced a durable and effective snowplow for-removing snow and ice from the beds of railways and equipped with means for delivering the debris from the rear of the machine in the longitudinal direction thereof or in a lateral direction from the side; but while the present embodiment of the invention is believed at this time to be preferable I do not limit myself to the structural details defined, as, on the contrary, I reserve the right to efiect such changes, modifications, and variations as may fall properly within the scope of the protection prayed.
